I thought I did a really good job teaching the laws of exponents in my Advanced Pre-Algebra class until it came time for the quiz. There were SO MANY misconceptions still. It seems as though a lot of them had been exposed to and memorized a lot of the properties without a lot of conceptual understanding of the topic which led to a lot of mistakes on the quiz. I quickly came up with this Exponent Matching activity to quickly review and reinforce the concepts. Each student received a card and then traveled around the room looking for the three classmates that had a card with an equivalent exponential expression. Once everyone thought they had found the right spot we debriefed as a whole class. Some groups ended up with too many people in them and others not enough so we talked as a class about those cards to find the right group for them. A few students never found a group so we also evaluated their card as a class to help them find the right spot. As a follow-up homework assignment students created their own set of four equivalent exponential expression cards. Students shared that this follow-up homework activity was critical to their understanding. Feel free to edit as needed to meet your classes needs, it really worked for us!
